a few days ago i updated avast, since then i haven't been able to access the internet without disabling avast's shield control first.
I'm using avast! free anti virus 5.0.677, my pc is windows vista. I have never had this problem before :'(
-
Lets start with the usual culprit:
What is your firewall ?
Does it allow avastSvc.exe internet access ?
- If it does delete the entry for it and try to browse, this should force the firewall to ask permission again.
What did you update from ?
-
I'm not sure what firewall I'm using, and how could i check if it allows avastSvc.exe internet access.
sorry I'm not very experienced with this kind of stuff.
and it was an auto update yesterday
-
If you don't know what your firewall is, then it is likely that it is the windows firewall that came with your Operating System (OS). This is disabled by default in Vista, so it shouldn't be blocking anything.
If you open the Control Panel, Security Center (winXP and possibly Vista also) and that should tell you what your firewall is.
Well an auto update would be for the virus signatures and as such isn't changing any avast processes like the avastSvc.exe file, so even if you have a 3rd party firewall installed it shouldn't see the file as having changed and block.
-
it just says windows firewall or just firewall.
-
That is as I said then just the default firewall that comes with windows and shouldn't be blocking anything.
Try this, http://www.mydigitallife.info/2007/06/18/repair-and-reset-windows-vista-tcpip-winsock-catalog-corruption/comment-page-1/ (http://www.mydigitallife.info/2007/06/18/repair-and-reset-windows-vista-tcpip-winsock-catalog-corruption/comment-page-1/).
There is a cool called WinSockFix.exe and you can get it from here, http://winsockfix.en.softonic.com/ (http://winsockfix.en.softonic.com/), that should work on Vista (but it doesn't mention it on that page), but I don't know is what it fixes is what is wrong with your system. Its the only other thing that I can thing of right now.
That is me for the night, almost 4:15a.m. here.

The only problem is, there was no program update for Avast!. So your conclusion is at least premature.

I'm having the exact same problem with Avast Pro. If I disable the web shield I can surf just fine, with it enabled I am unable to so much as resolve DNS via the web browser.
Any ideas as to how to reset the web sheild or resolve the issue?

I would say my conclusion was pretty acuurate, I was in the middle of using my browser when Avast updated itself, and then all http traffic was blocked after either a definition update or software reconfig, then all http traffic is blocked. pretty open and shut really

As far as I know a VPS update can't corrupt your Windows Sockets configuration. (De-)installation of networking software can, or malware , or the removing of malware.

I understand red, in order for me to get , malware, virus I would have to execute that said file unless it was an exploit or /worm, im too careful for that to happen, as soon as avast webshield is terminated all is well, prob is avast!!!
-
No, the problem is a corrupt Windows Sockets configuration. And the question is what caused it. I only said other scenario's are possible. For example the Windows Update of last week.
Greetz, Red.
-
If it was windows update on tuesday week then WHY did it not happen immediatley after restart of said updates, the only update that has caused this is avasts.. cant say any clearer than that. why are you so dissmissive thats its not avast!!! when disabled web shield http traffic is allowed through when its enabled all traffic is blocked..... ::) clearly something that has changed in avast config has trashed with winsock. If it was a windows update then MS would have been on a fix and released already..
-
and if it was a corrupt winsocket then how come a winsocket reset didn't fix the laptop I'm having problems with? Didn't do a dang bit of good, granted I didn't try that reset before but the one just posted didn't help.

Hi to all of you,
I also updateted to Avast 5.0.677. All seemed to be fine. Today I had the same problem described before. Every time I started my Browser (Firefox) I received a question from my Firewall (Sygate) if I would allow Avast! Service (AvastSvc.exe) access to ocsp.godaddy.com.
Every Time I denie that question I couldn´t access the internet. Then when I allow Avast to do so, connection was fine. Perhaps it´s the same on your systems and your firewall remembers a further given answer.
After looking what ocsp.godaddy.com is, it seems to be a kind of SSL Certificate. Does anyone know what´s about?
Thank you for your answers - and don´t look on my bad english!

I'm not sure what version of Avast you're able to access, but I've been pestered to update to Avast 5.0.677. Why say something stupid like "no program update?"

Hello all,
I was having the same problem as most of you after installing Asvast 5 (couldn't connect; couldn't update; firefox connected to the net while IE wouldn't, blah, blah blah). I am running Vista 32 SP2, having had at one point or another: Mcafee, Comodo and Zone Alarm and, thanks to alot of you and your advice, I got all the uninstallers I could find to clear up any traces of said former FW's/AV's. YET STILL, I couldn't connect to the net through IE or update Avast.
Not sure if this will work for you but after having read countless forums and spending 3 DAYS trying to fix this (the Avast AV rating's just couldn't be pasted up-and for free) I found this little , itty bity thing that let Avast connect (at least for me).
Purely by accident I went into: Network and sharing (my LAN settings); clicked on view status then properties and LOW AND BEHOLD, there was an old, old setting for comodo still there from 2 years ago I had no idea was still active. Soon as I deleted it, Avast worked, updated (quite quickly I might add) the whole bit!
Again, not sure if this will work for any of you but I finally got it going! THANKS to all of you for the advice on how to clean up old crap from my "puter". I appreciated all I've read and plan on spreading the info wherever I can!
Good Luck,
Therobbie1

Thanks therobbie1. Some software leave remnants behind even after using their uninstallers. We are lucky that Avast did a good job and cleans itself up well and doesn't do that. But I usually did around my machine looking for remnants for software known to leave little remnants behind...usually you can find them in Safe Mode under Search, but you found a different way to do it. Good for you. ;)
